VENTI LATING CARS.

SPECIFICATION forming part of Letters Patent K053355583, dated January 4, 1887.

Serial No. 199,706. (No model.)

To all whom it may concern.-

Be it known that we, J OsEPI-I A. BU KLEY and CHARLES J. KOEFOED, both of the city and county of San Francisco, State of California, have invented an Improvement for Ventilating Cars; and we hereby declare the following to be a full, clear,and exact description of the same.

Our invention relates to a device for supplying cars with pure cool air; and it consists in the construction and combination of devices, all of which will be more completely described by reference to the accompanying drawings, in Which Figure l is a longitudinal vertical section of the car, showing our invention. Fig. 2 is a transverse section. Fig. 3 is a horizontal section. Fig. 4 is an enlarged section of the washing and refrigerating tanks. Fig. 5 is a horizontal section showing the pipes on the ceiling of the car. Fig. 6 is a perspective view of the fan-blowersand connecting-hose.

A are the wheel-trucks-such as are used beneath ordinary railroad-carriageswhich are supported upon swivel-pins, so as to allow the wheel-trucks to move independently ,of the carriages in turning curves.

Upon the truck-frames we fix the fan-blowers B and C so that they will stand in opposite directions, one being so arranged as to discharge air when the car is running in one direc- .tion, and the other so as to discharge air when it is running in the opposite direction.

Upon the axle E ofthe car-wheels are fixed belt-pulleys F,or friction wheels or gears, and from these belts or intermediate gearing trans- -mit the power to the fan-shaft, the power being so arranged as to produce the necessary rapidity of motion to the fan and giving the proper blast of air The pulleys may be split, so as to be easily put on or removed, and they are easily fitted to the rough unfinished axles by means of rubber shims fitted inside the base of the pulley. Flexible pipes or hose G extend from the discharge-openings of these two fans and connect them with the fixed pipes H uponthe body of the car, so that while the trucks and the fans and the mechanism attached to them are allowed to move freely to suit the curves of the road, connection between the fans and the pipes, which are rigidly secured to the body of the car, will be properly maintained without danger ofbreaking or separating the joints. Each fan has a flexible pipe connecting it with the pipe H, and a cook or valve may be fitted so as to close one while the other is working. These pipes H are provided with suitable cocks or valves, by which their supply of air is regulated and led upward and discharged into atank or receptacle, I, suitably located in the ear, and containing water, above or below the surface of which the air is discharged, so that any dust or foreign matter which may be brought in by the blowers ma be delivered into the water in the tank and re-' tained by it, settling to the bottom in the form ofa sediment. The tanks or receptaclesmay be placed horizontally, or in an inclined position, orwith an incline bottom, as is most suitable, and they may also contain ice or other refrigerating or cooling substances.

In the present case we have shown a separate ice-receptacle, I, just above the waterchamber, the ice resting upon a perforated screen or tray, through which the air may pass upward, and the water may drip down into the water-tank.

water-tank, and b is a float connected with it, so as to raise it and discharge surplus water and sediment when it accumulates.

upward through a pipe, J, which leads to the upper part of the car and this pipe is connected with horizontal distributing-pipes K, as shown. A screen or straineris fixed in the pipe where it leaves the water-tank, to prevent the passage of any foreign substance which may not have been retained in the tank. The vertical pipe J has fixed within it at intervals conical diaphragms or flanges J, which inclined downward, having a central portion left open, so that the air may pass freely through. By means, of these conical partial diaphragms any water or moisture which may be carried up from the receivers, into which the air is first discharged, may be detained, and will fall down the sides of the tubes. These horizontal pipes may pass through the car at any desired point, but preferably along each side of the upper central portion, having valves or openings through which the air may be discharged at intervals through the length of the are secured to the inner side of the pipe and 7 a is a discharge-valve in the bottom of the r After the air leaves the receivers it passes car. The cold air will, by reason of its weight, sink toward the bottom of the car, while the lighter air will rise, and may be discharged through suitable discharge-openings. In the present case we have shown the distributingpipes opening upward into a funnelshaped discharge near one end of'the car, and pro vided with a cock or valve, which may be opened or closed, so as to decrease or increase the pressure of air in the pipes within the car and the consequent supply therein. These funnel-shaped pipes may be placed at intervals throughout the length of the car, if desired.

A branch pipe, L, may be led into the closets of the car, discharging upwardly through a conical discharge-pipe, as shown, and having openings by which air may be supplied to these closets, so as to perpetually renew and purify the same.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is

1. The fan-blowers mounted in pairs upon the wheel-trucks of cars, so as to act in opposite directions, and so that their movements correspond with those of the wheels journaled thereon, pulleys and belts by which power is transmitted from the wheels or wheel-axles to the fans, a water tank or reservoir within the car-body, into which the air from the blower is discharged, an independent chamber locatedaboveand com municatingwith the water-tank and containing ice, through which second chamber the air is conveyed, horizontal pipes K at the top of the car, having discharge-openings, and pipes J, connecting the horizontal pipes with the ice-chamber, in combination with the funnel-shaped upwardlyopening pipes, through which the air passing through the pipes maybe partially discharged, so as to create a draft for the removal of foul air,while at the same time providing a supply of fresh air to take its place, substantially as herein described.

2. The blower deriving its power from the wheel-axle of the car, air-conveying pipes extending from the blower passing into and through the car, in combination with the water tank or reservoir placed between the blower and the interior of the car, into which the air is first dischargedto deprive it of its dust and foreign matter, a refrigerating or ice chamber connected with the water'tank, and the beveled flange or flanges within the air-conveying pipes, whereby moisture is arrested and prevented from passing up into the pipes, substantially as described.

3. The fan blowers, conveying and distributing pipes, and intermediate washing and refrigerating chamber or chambers, in combination with an automatic valve set in the bottom of the water-chamber, whereby any increase or surplus of water and sediment may be discharged, substantially as herein described.

4. A fan-blower deriving power from the ,car wheels or. axles, discharging air into the washing and refrigerating chambers within the car, in combination with the pipes extending therefrom through the upper portion of the car, having elongated discharge-openings at intervals, and funnel-shaped upward-opening pipes, through which the air-pipes may be discharged and produce a draft, carrying ofl' the heated air, substantially as herein described.

In witness whereof we have hereunto set our hands.
